erdas imagine mode
By LAKSHMI,
I am doing my masters in geoinformatics. My thesis topic is MODELING OF SPATIAL OBJECTS FOR LAND COVER CLASSIFICATION USING FUZZY TOPOLOGY. I need to calculate a measure of the distance of a pixel from its mean pixel. for that I need to calculate (x-m)T* (cov©)-1 * (x-m)
where x- pixel vector
m-mean vector of the sample (signeture for supervised classification
T-transpose function
cov©-covariance matrix of the sample
I have a raster image from which x can be taken, mean and covariance matri
MODIS 'State_1km' questions
By Jr.,
Hey all, I'm relatively new to the remote sensing side of the GIS field, so I apologize if this seems a basic question, but I can't seem to wrap my head around how the SDSs are set in a daily MODIS dataset (like MOD10A1 or MOD09GA). As you approach the poles, the number of times a particular pixel is imaged rises. My question is, how does this affect the setting of the 'State_1km' SDS flags? From what I've gathered, they are based off the observation with the highest quality, but do they then
How to write an algorithm in Erdas Imagine Model maker ?
By zoarder,
Dear All, i hope you all are fine. I am doing my Msc thesis on Urban Heat island modeling. One part of the model i have a calculation regarding LST calculation from Landsat ETM image. I am using mono-window technique. Manually i calculated LST for one pixel and its ok. But the problem is working in Erdas imagine model maker. My algorithm is showing error. My model is as follows in erdas model maker.
{ -67.355351 ( 1-$n4_memory - $n6_memory ) + ( 0.458606 ( 1 - $n4_memory - $n6_memory ) + $n4

Education online
By randy,
I am wondering if anyone can share some information about online degrees. I am trying to get an online Bachelor's degree in a field directly relating to GIS. I found a program that looked pretty good and a school called American Sentinell, but that turned out to be a dead end. They no longer offer that degree program. I have been going down a list of schools that I received from American Sentinell, and so far most of them are a dead end. The closest I've come is a degree in Information Tech
